Thalidomide and lenalidomide are FDA approved for the treatment of multiple myeloma, and along with pomalidomide are being investigated in a variety of other cancers. Although these agents display immunomodulatory, anti-angiogenic and anti-apoptotic effects, little is known about the primary mode of therapeutic action in patients with cancer. This paper describes a microarray study of the in vitro and in vivo effects of these drugs, and contrasts the difference in gene profiles achieved in the two models. In the current study, Agilent whole mouse genome oligonucleotide microarrays (44 K) were used to examine alterations in gene expression of colorectal cancer cells after treatment. Venn analysis revealed a divergence of gene signature for pomalidomide and lenalidomide, which although similar in vitro, different in vivo. Several clusters of genes involved in various cellular processes such as immune response, cell signalling and cell adhesion were altered by treatment, and common to the three drugs. Notably, the expressions of linked genes within the Notch/Wnt signalling pathway, including kremen2 and dtx4, highlighted a possible novel mechanistic pathway for these drugs. This study also showed that gene signatures were not greatly divergent in the models, and recapitulated the complex nature of these drugs. Overall, these microarray studies highlighted the diversity of this class of drug, which have effects ranging from cell signalling to translation initiation.
